BOTTLE-STOPPER.

Y SPECIFICATIQN forming part of Letters Patent No. 359,373, dated Marchl5, 1887. Application filed January 20, 1887. Serial No. 294,898. (Nomodel.) Patented in En g'and December 7, 1885, No. 15,015.

' zo 1.5,0150 of which thefollowing is a specification.

This invention relates to means of stoppering bottles, particularly suchas contain aerated liquor, by applying a cork in combina- 15 tion with acap so arranged as to retain the cork in its place notwithstandinginternal pressure acting` on it, and to facilitate the extraction of thecork without requiring a corkscrew, as will be explained with referenceto 2o the accompanying drawings. v

Figure 1 is a vertical section of a bottleneck stoppered according ,toour invention. Fig. 2 is a side View, and Fig. 3 is a plan of the cap. z5 The top ofthe bottleneck has formed on it a screwthread, a, preferablyof rounded form, as shown.

metal, is made with a corresponding thread, b, and with a central hole,which has its edge 3o serrated or toothed, as shown at o, theinwardly-projecting teeth or serrations being benta little downward. Thecap being screwed on the bottle-mouth, a cork (indicated by the The cap,which may be of thin A dotted lines cl in Fig. l) is driven in. Inentering it freely passes the bent-down teeth c; 3 5 but these act asbarbs, preventing the cork from being forced out again by internalpressure. When it is desired to open the bottle, the cap is unscrewed,the cork coming with it. The upper edge, e, of the cap is preferablymilled 4o to give better hold for screwing and unscrewing. A corkwasher, j', may be placed under the cover of the cap.

Having thus described the nature. of this invention and the best meansWe know for car- 4 5 rying it out in practice, we claim- Abottle-stopper consisting of a cork and cap, the cap being made with ascrew-thread to't a thread on the exterior of the bottlemouth, and witha central serrated hole through 5o which the cork is forced,substantially as and for the purposes herein set forth.

In testimony whereof we have signed our names to this specication, inthe presence of two subscribing witnesses, this 6th day of J an- 5 5uary, A. D. 1887.
